[OPEN-EXTJSIV-1804]Ext.ComponentQuery xtype

I believe there’s an issue with the way alias’s get registered in their components as xtypes. For example, I’m try to query a radio button, this.down(‘radio’) and am unsuccessful, however, I’m able to query on ‘radiofield’. When I rearrange the alias array so that widget.radio is first, I’m then able to query on it, but not on radiofield.
